🎯 Use case
This file lives under “utils/”, which covers cross-cutting helpers (shell, tempfiles, settings, messages, process input, …). On the API surface it exposes stripDisplayTags, stripDisplayTagsAllowEmpty, and stripIdeContextTags — mainly functions, hooks, or classes. What the file header says: Matches any XML-like `<tag>…</tag>` block (lowercase tag names, optional attributes, multi-line content). Used to strip system-injected wrapper tags from display titles — IDE context, slash-command markers, hook output, task notifications, channel messages, etc. A generic pattern.
Generated from folder role, exports, dependency roots, and inline comments — not hand-reviewed for every path.
🧠 Inline summary
Matches any XML-like `<tag>…</tag>` block (lowercase tag names, optional attributes, multi-line content). Used to strip system-injected wrapper tags from display titles — IDE context, slash-command markers, hook output, task notifications, channel messages, etc. A generic pattern avoids maintaining an ever-growing allowlist that falls behind as new notification types are added. Only matches lowercase tag names (`[a-z][\w-]*`) so user prose mentioning JSX/HTML components ("fix the <Button> layout", "<!DOCTYPE html>") passes through — those start with uppercase or `!`. The non-greedy body with a backreferenced closing tag keeps adjacent blocks separate; unpaired angle brackets ("when x < y") don't match.
